Other features include a stainless steel case, a mineral crystal window, and water-resistance to 99 feet (30 meters). This is an automatic mechanical watch. Automatic watches do not operate on batteries, instead, they are powered automatically by the movement of the wearer’s arm. If the main spring in your automatic watch is not wound sufficiently, timekeeping may become less accurate. In order to maintain accuracy, wear the watch for 8 hours or more per day, or manually wind the main spring by turning the crown.

I can't seem to find a way to do that.** A: The movement this watch is equipped with is called the 7S26. It is the least expensive version of the 4R family of movements. As such it lacks the ability to hack or handwind. Hacking is the ability for a movement to stop its second hand. With a quartz watch this is easy, but a mechanical watch needs a spring or a clutch to stop the second wheel. Seiko watches with the 4R35 and 6R series of movements have hacking and hand winding along with other upgrades and accuracy improvements. **Q: Got this a week ago, and I've been wearing it everyday, but it stops every couple of days. Does it have to left faced up, flat when not being worn?** A: I know the original question is from 3.5 years ago; but, for the benefit of new people researching this watch: This movement has a maximum of about 36 to 40 hours of reserve when fully wound (advertised ~41 hours). To expect an automatic watch at this price point to go longer than that is just ludicrous. If you have worn it all day, that should get you through at least overnight. Give it the "Seiko shake" (hold face up and shake it back and forth) for about a minute to ensure it lasts through the night...I don't think you need to, but it adds a bit of tension to your mainspring and can't hurt. If you take it off Friday and not move it until Monday morning, it would be an unrealistic expectation that it will still be running. **Q: Are hands visible in the dark?** A: There are two common way to make 'glow-in-the-dark' things: radioluminescence and phosphorescence. Radioluminescence is when a material lets off light on its own because it's slightly radioactive. High-end watches use radioluminescence for their features. Phosphorescence is the much cheaper alternative that's commonly used in glow-in-the-dark plastic, toys, and paint. The key difference is that it doesn't generate its own light--it's charged by sunlight like a battery and releases at night. This watch uses phosphorescence for its features. If you wear it outside, uncovered, and in the bright sunlight all day, it should stay glowing all night long. If you work indoors or cover your watch with your sleeve during use, it may not make it all the way through the night. This effect will also weaken over time--but rest assured it should still glow for a few years at the very least. **Q: Are the canvas bands that come with the watch replaceable? If so, where can I find them?** A: Hello John, you can certainly replace the band and there are many beautiful bands on amazon. I am not sure about the specific canvas band but you should be able to find a nice one for your watch. Just look at the technical details for the band size and happy hunting. PS: You might not want to spend too much time and money buying a new band as the watch is prone to failure after a couple of months. Mine is caputt and in the trash already and even with the warranty, you will spend more time and money sending it back and forth than the $60 you paid for it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent, versatile, classic watch. Affordable price. *by on Reviewed in the United States February 3, 2015* This is a great watch. So much has been said in other reviews that I won't add to the noise but one area that hasn't been thoroughly discussed I feel I may have something to add to is the color of this specific model (SNK807). As an artist color is paramount and something I'm sensitive to. So having only the pictures online to go on was something of a leap of faith for me, the luxury of holding something in our hands before we buy it is foregone when purchasing over the Internet. The user posted pics all seemed to vary from one another, either being super saturated green or nearly black. So I've posted my own pics which are very color accurate. The first pic is in broad daylight, which is as green as this watch gets. The other two are under normal room lights (daylight fluorescents). My point is, this is a dark olive drab with almost no green at all, which is exactly what I had hoped for. Another aspect of this watch I really like is its versatility. You can strap on a fancy leather strap and its a classy dress watch, or throw a NATO style strap on and head into the wilderness for years at a time and not worry about anything, especially batteries (this is a fully mechanical automatic watch). It may not be obvious, but this is also related to color. The neon green strap this watch is shipped with is bright and has the effect of making the watch face appear more green. Google "simultaneous contrast" for more, or believe me when I say your choice of strap color has a huge influence on what color the watch appears to the eye. I bought a very nice $30 "OD phalanx" strap from Crown and Buckle and am very pleased, plus the khaki NATO strap, both of which are pictured above. My sample ran less than 30 seconds fast for the entire first week I owned it, and has been plus or minus two seconds a day since then. From what I've read of other automatics, this is outstanding especially for the price, and I couldn't be happier with this watch. I have no idea what the negative reviews are talking about, unless they bought from someone other than Amazon and received Feikos. Another thing I'd like to clarify is the Lumibrite. It's brightness and longevity are directly proportional to how much light YOU expose it to before it's in darkness. Ten to twenty minutes in direct sunlight and it will glow like its radioactive for hours. Only room lights and it's a subtle glow for a couple of hours. I didn't really want this feature, but now that I have it I love it. Really, the pattern it has when all the lights are out is really classy. It's like an old Rolex design. Very nice, Seiko. Thanks for a great watch. Will buy again, even if it's just to get the other colors! ### ⭐⭐⭐⭐⭐ This is a GOOD watch. No resets at all. "Edit 4" *by on Reviewed in the United States December 25, 2013* A few years ago I had this watch stolen from me by someone who apparently liked it as much as I did. I tried not to think about it because I'd bought some higher end automatics, but I really missed it so I finally broke down and bought it again. In its price range there is no better choice in automatic wristwatches. My first one was a perfect watch, and its replacement so far has been every bit as good as the one I got nine years ago. Supposedly Seiko is slowly phasing these out on favor of its replacement, which has hand winding, and hacking, but also a 300% higher price tag. So if you are undecided, let me say again, buy one now. Do not wait, in the future a used one might be your only option.***EDIT***Over a year and still going strong. Not my prettiest watch, but my most reliable and practical one without a doubt! One of these days I want a cream colored one as well.***Edit*** A month in and still the best mechanical watch I have ever had ***Edit***So far I'm liking it very much. "Well made, keeping good time. Nicely styled tribute to the old army issue watches of WWII. Whats nice about it is it is very unisex, its small enough to be worn on a woman of medium build, yet looks quite presentable on a man.***Edit*** Just did a test run for reserve power. Took it off, laid it down flat on its back on a table and it ran for 47 hours! 47 hours and 14 minutes to be exact. So yes, I can change to another watch and it takes approx two days to run to a stop. That's assuming its been worn for a day before it. It gains about a minute a week. For a mechanical watch that is very good. If you don't expect time creep at ALL, do not buy an automatic watch. You will only be happy with quartz. ***Edit***The only thing I don't like about it is I was told the lume was very bright and lasted a long time. The Lume is pretty weak actually.As to warranty, notice that when the seller is directly from Amazon it has a three year warranty. But when its sold by a third party seller and just fulfilled by Amazon it makes no such claim. (And contains no warranty card) So by all means buy it, but make sure its sold AND fulfilled by Amazon. The sellers seem to rotate over a period of days, sometimes third party, sometimes not.I've noticed, third party grey market watches and Feikos are a real problem. Some of the negative reviews are pretty obviously based on fake watches. Yes, fake Seiko 5s are a real thing and a serious problem. (Google Feiko) If your watch was fulfilled by Amazon and not sold by them as well, it probably didn't have a box, and certainly had no warranty card. IF it had no warranty card do NOT accept it and get a refund. Get one directly from Amazon only and not one of their shifty "fulfillment partners"I've seen reviews on here that are clearly Feikos. Whatever you do, be sure you get yours directly FROM Amazon, and NOT from a company using Amazon for fulfillment.Going to test it tomorrow and see how long it really runs without being worn. The watch I have is very solid, and so far has been excellent. The only thing that CAN explain some of the negative reviews is Feikos creeping into the supply chain. ### ⭐⭐⭐⭐ Watch never needs winding... *by on Reviewed in the United States April 16, 2021* This is a nice watch and it keeps pretty good time.I did not like the wristband, because it was nearly too small for one, and it had the leather backing on the holes for two. This backing eventually dog ears and makes it harder to put the band on. I switched it out with a Speidel twist-o-flex and had a jeweler adjusted it to my wrist size. It now fits like a bracelet and there's no pinching or hair pulling with it. It's now an easy on and easy off watch.It's water-resistant, which means it will not get terribly hurt if it gets wet. Even so, I take it off if I'm taking a shower, bath, or if I'm washing dishes. No sense in pushing the limits of it.Setting the time is really easy. Set your time first, by pulling the crown out two clicks. Make sure you're turning this in a clockwise fashion, because turning it counterclockwise can be done , but it's hard on the watch. Turn the hands until you see the date change. Continue turning until you reach the current time. Make sure your current time is during the daytime, sometime between 4 a.m. and 8 pm.After you have set the time, push the crown in one click and set your date, turning one way , and the day, turning the other way.Your time, day and date should now be set. Push the crown all the way in now and give it two or three turns. You can now put it on your wrist and the motion of your wrist will continue winding The Watch. I've been wearing mine for a week now and have yet to wind it up at all. The motion of your wrist will take care of that for you.The quality of this watches fantastic and I expect this watch to last at least 10 years with proper care, and 20 to 30 years if I don't abuse it. I think you would love this watch and I do recommend it. It is a little bit on the small side, which is not fashionable by today's standard, but I like the size of it, because it's not cumbersome nor is it noticed so much.You may be wondering why buy a watch, since you have a cell phone and you can find the time on there. I discovered that turning on my cell phone every time I want to know the time was becoming cumbersome and not always easy if your hands are full. It's so much easier to just twist your wrist and look at the time this way. The fact that this watch never needs batteries, is a plus. ## Frequently Bought Together - Men's SNK805 SEIKO 5 Automatic Stainless Steel Watch with Green Canvas - BARTON Canvas Quick Release Watch Band Straps - Choose Color & Width - 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, or 24mm - Ritche Christmas Gift Quick Release Leather Watch Bands Genuine Watch Straps for Men Women- 18mm 20mm 21mm 22mm 23mm 24mm Top Grain Leather Watch Strap, White Elephant Gifts, Stocking Stuffers for Men --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/1096340-seiko-mens-snk805-5-automatic-watch](https://www.desertcart.co.uk/products/1096340-seiko-mens-snk805-5-automatic-watch) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-05*
